Error: Skin null does not exist - adyen

Question

From my controller, I'm trying to make a post request to https://test.adyen.com/hpp/select.shtml but I continue receiving this error
Error: Skin null does not exist
This is part of my code
$paramsRequest = array (
'merchantReference' => 'reference',
'paymentAmount' => 10,
'currencyCode' => 'EUR',
'shipBeforeDate' => '2017-11-29T13:42:40+1:00',
'skinCode' => 'f8My4RJC',
'merchantAccount' => 'TestNL076',
'sessionValidity' => '2017-11-29T13:42:40+1:00',
'merchantReturnData' => 'string',
'shopperEmail' => 'shopper#gmail.com',
);
$hcma = '8382E2...';
$paramsRequest['merchantSig'] = Util::calculateSha256Signature($hcma, $paramsRequest);
return $this->handlePostRequest($paramsRequest, 'https://test.adyen.com/hpp/select.shtml');
and to handle the request
protected function handlePostRequest($data, $url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_USERPWD, 'admin' . ":" . 'password');
curl_setopt($ch, CURLOPT_POST, count($data));
curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return $result;
}

Are you trying to perform a lookup of available payments? If so, use the end point.
https://test.adyen.com/hpp/directory.shtml
Otherwise the select.shtml an endpoint to redirect shopper's browser when you want them to enter in information or send them to their bank. Here's link to adyen's local payment method docs.
